Hello, I’ve been using Sketchup 2023 for a few months and this is my first time I’m facing this problem. When I rendered my 3D interior model (with Vray 6.00.02) , there are very strong shadow lines from the ceiling to some part of the wall and kitchen cabinets. I’ve read some similar topics but that’s quite unhelpful for me. Some things I’ve tried (but still doesn’t work):
set the secondary rays to “brute force”
set the environment GI to 100
lowering the light sources by 2cm from the ceiling
turning on denoiser
turning off progressive
set the cone angle of some lights to 179.99 degrees
I don´t think so, It´s actually almost impossible to tell you what´s the problem without checking it. If the file is too big you can use wetransfer or any other platform you wish and share the link
That’s exactly what it looks like to me - the recessed ceiling light is illuminating the room and the edge of the recess is blocking the light and casting a shadow.
Also you’ve mentioned you’ve set the cone lights to cast to 180 degrees - could it be that the spotlights from the pendants are illuminating everything below the shadow more?
Possibly, but not sure. The light source seems to be from a horizontal source and object edge given that the line on the recessed cabinet face is the same level as the one on the proud cabinet face. That light is definitely not coming from above.
Test it by turning off the light sources one by one.
It doesn’t seem reasonable that the pendant lights would be responsible for the shadow on the cabinets and the wall. Id start with the light up in the tray ceiling.
1st attempt : turning off the omni light inside pendant…it works, but the shadow on the cabinet remains (well it is normal, but i don’t think it’ll look that dark irl)
It would if the light source were exactly at the level of the edge of the shade.
That might be what makes it that way, even thought a real light fixture like that wouldn’t do that; the source being up in there would cast a cone and it would make hyperbolic scallops on a vertical surface
I wondered if that was a coincidence. I could see tiny glint of light at the bottom edge coming from cracks in the cabinet doors it looks like. You can still see them.
i’ve checked the model, there is no light inside the cabinet…and i don’t see the glint of light from the cracks you’re talking about…mind if you show me where it is?
nothing changed much, maybe because i’ve turned off the pendant lights. even if this causes those weird shadow line, turning off the recessed lights are not desirable (for the sake of lighting accuracy). is there an alternative to this?
I agree if they were real world lights, but some lights in V-Ray are unworldly. If the light were a hemisphere with a light source that’s simply a glowing face invisible to the camera, the results could be weird.
Agreed but I think the source of the shadows must be above the the pendant lights. Maybe there’s an invisible light source? Your eagle eyes caught those notches in the shadow. Maybe like you suggested it is the recessed can lights.
